Strength is determined by three factors: the muscle’s efferent pathway, the quantity of muscle and the quality of muscle. Both the muscle and the efferent pathway can be affected by stroke, either by disuse or direct assault on the central nervous system. As a result, stroke often results in loss of functional strength.
Muscle strengthening as an intervention is designed to improve the force-generation capacity of a muscle. Its application for stroke focuses on strengthening of the hemiplegic limb and enhancing functional abilities. Various types of muscle strengthening programs have been designed for the stroke clientele. Those included in this module include resistance training, force feedback, functional tasks and weight bearing tasks.
